Enable/Disable ContextDragBehavior based on property

[GundlackFlorian]

Hello,

How could i enable/disable a ContextDragBehavior based on a property ?

Here is the code i'm using.

<DataGrid.Styles>
    <Style Selector="DataGrid.ItemsDragOut DataGridCell">
        <Setter Property="Interaction.Behaviors">
            <BehaviorCollectionTemplate>
                <BehaviorCollection>
                    <ContextDragBehavior Handler="{Binding DragHandler, RelativeSource={RelativeSource TemplatedParent}}" />
                </BehaviorCollection>
            </BehaviorCollectionTemplate>
        </Setter>
    </Style>
</DataGrid.Styles>

Thanks in advance.
